According to Chapter 23, how did Sai Baba address the unspoken doubt of the Yogi who saw Him eating onions?

Chapter 23 provides a fascinating account of Sai Baba's omniscience. When the Yoga practitioner visited and silently doubted Baba's ability to help him after seeing Him eat bread and onions, Baba directly addressed the man's inner turmoil without being asked. Turning to Nanasaheb Chandorkar, Sai Maharaj said, 'Nana, only those whose digestion is strong should eat onion. One who has the strength to digest it may eat onion freely.' This statement, as recounted in the chapter, was not a literal dietary comment but a powerful spiritual metaphor. The Yogi instantly understood that Baba was referring to the 'digestion' of spiritual truths and the ability to see beyond outer appearances, which completely dispelled his doubts and caused him to surrender.
